Looking at a 78 300D wanna know if it's a good buy

Hi, I am new to the forum. I just have one question. I came across a 1978 300d with only 98,000 miles on the dash. I spoke with the owner of the car and she asid the car has sat for more than 10 years when her husband died. Would it be worth to buy it for $200.
